Why Kenyan Bus Passengers Have Started Yelling at Their Drivers

From the Daily Stat at HBR: Inexpensive messages urging Kenyan minibus passengers to heckle and criticize their drivers for being reckless caused a 60% reduction in insurance claims involving injury or death, say James Habyarimana and William Jack of Georgetown University. Stickers carrying messages such as “Don’t just sit there as he drives dangerously! Stand up. Speak up. Now!” and showing graphic illustrations of severed feet and legs were placed inside the buses. Drivers were given incentives to leave the stickers in place.
